Processes for the production of high strength polyethylene tape articles from high strength ultra-high molecular weight multi-filament yarns, and to the tape articles, fabrics, laminates and impact resistant materials made therefrom.
摘要:
The invention relates to a low dielectric loss material comprising a plurality of polyolefin tapes forming a sheet and a coating disposed onto said sheet, wherein said coating comprises an epoxy resin.
摘要:
The invention relates to a material comprising at least one laminate component containing polymeric fibers wherein the material has a loss tangent of less than 8×10−3 radians as measured at a frequency chosen from the group of frequencies consisting of 1.8 GHz; 3.9 GHz; 10 GHz; 39.5 GHz; and 72 GHz.
摘要:
Provided is a method for manufacturing a composite material having a thin thickness, a low thermal expansion coefficient and a high thermal dissipation characteristic, the composite material manufactured by the manufacturing method, and a copper clad laminate using the composite material. The composite material using a unidirectional carbon fiber prepreg fabric manufactured through the steps of: manufacturing a unidirectional carbon fiber prepreg; cutting the manufactured unidirectional carbon fiber prepreg to a given width; weaving the unidirectional carbon fiber prepreg cut to the given width to form a fabric; and curing the woven unidirectional carbon fiber prepreg fabric.
摘要:
A ground cover sheet material for use in agriculture is woven from warp and weft tapes of a plastics material and at least some of the warp or weft tapes have a greater width and/or thickness than the weft or warp tapes, or the material includes a higher density of warp or weft tapes relative to the weft or warp tapes per unit area, or includes slits through the tapes, or the tapes are folded lengthwise, all optionally in one or more high water flow through lengthwise extending parts of the material. In one embodiment the material is woven from warp or weft tapes some having a rectangular or square cross-section and some having a circular or oval cross-section. In some embodiments the material is also a reflective material.
摘要:
A slit yarn wherein both side parts of the slit yarn are folded one or more times, and the folded width is substantially uniform along the direction of length of the yarn. In this slit yarn, when the width is measured at 20 or more points at intervals of 0.5 m, and the fluctuation coefficient X shown in the following Equation (1) is calculated on the basis of the average value W(avg) and the standard deviation W(σ), this X is (for example) approximately 4% or less. Furthermore, in the slit yarn of the present invention, the abovementioned folded parts are ordinarily shape-set. X(%)=W(σ)/W(avg)×100 (1)
摘要:
The waterproof/breathable moisture transfer liner for a snowboard boot includes an inner liner selected from technically advanced fabrics which are carefully selected. A series of layers are provided outside the inner liner including foam material layers, breathable membranes, a supportive mesh or a moldable foam, and an outer shell fabric. The applicability of the liner to alpine, cross country and hiking boots, along with appropriate variations for each application.
